The white and black pavement structure is usually adopted in the reconstruction of cement concrete pavements. Though long -term use of white and black pavement structure damages the base course or the roadbed, excavation is not recommended to deal with the base course or the roadbed. Therefore, this article puts forward an effective and environmentally friendly technology - -polymer grouting repairing technology, describes the physical characteristics and mechanical properties of polymer grouting material and then introduces the application and construction technology of polymer grouting technology in white and black pavement maintenance as well as the assessment of the grouting effect.
